I’ve downloaded the Panasonic P2 contents Manager application and installed in on a current 12-core MacPro. Although it does access the card or a copy of the contents folder copied to HDD and displays the clips as thumbnails without issue, it fails to play the clips in the viewer when double clicked. I get audio but no video. The clips are AVC-Intra 100 and the Quicktime codec for AVC-Intra has been downloaded and installed. The AVC-Intra component is in the Quicktime folder. This Mac is running Snow Leopard (10.6.8) and does have Final Cut Studio 3 installed.
I also installed the application on an older MacPro running the same FCP studio version, but running Leopard and Quicktime 7.6. The clips play fine on that machine.
